Sustainable development calls for a larger share of intermittent renewable energy. To mitigate this intermittency, Compressed Air Energy Storage (CAES) technology was introduced. This technology can be made more sustainable by recovering the heat of the compression phase and reusing it during the discharge phase, resulting in an adiabatic CAES without the need for burning of fossil fuels. The key process parameters of CAES are temperature, pressure ratios, and the mass flow rates of air and thermal fluids. The variation in these parameters during the charge and discharge phases significantly influences the performance of CAES plants. In this chapter, the transient thermodynamic behavior of the system under various operating conditions is analyzed and the impact of heat recovery on the discharge phase energy efficiency, power generation, and CO₂ emissions is studied. Simulations are carried out over the air pressure range from 2,500 to 7,000 kPa for a 65 MW system over a five-hour discharge duration. It is also assumed that the heat loss in the air storage and the hot thermal fluid tank is insignificant and standby duration does not impact the status of the system. This result shows that the system exergy and the generated power are more sensitive to pressure change at higher pressures. This work also reveals that every 10°C increase on the temperature of the stored air can lead to a 0.83% improvement in the energy efficiency. The result of the transient thermodynamic model is used to estimate the reduction in CO₂ emissions in CAES systems. According to the obtained result, a 65 MW ACAES plant can reduce about 17,794 tons of CO₂ emission per year compared to a traditional CAES system with the same capacity.

Open data are characterized by a number of economic, environmental, technological, innovative, and social benefits. They are seen as a significant contributor to the city’s transformation into smart city. This is all the more so when the society is on the border of Society 5.0, that is, shift from the information society to a super smart society or society of imagination takes place. However, the question constantly asked by open data experts is, what are the key factors to be met and satisfied in order to achieve promised benefits? The current trend of openness suggests that the principle of openness should be followed not only by data but also research, education, software, standard, hardware, etc., it should become a philosophy to be followed at different levels, in different domains. This should ensure greater transparency, eliminating inequalities, promoting, and achieving sustainable development goals (SDGs). Therefore, many agendas (sustainable development strategies, action plans) now have openness as a prerequisite. This chapter deals with concepts of open (government) data and Society 5.0 pointing to their common objectives, providing some success stories of open data use in smart cities or transformation of cities toward smart cities, mapping them to the features of the Society 5.0. We believe that this trend develops a new form of society, which we refer to as “open data-driven society.” It forms a bridge from Society 4.0 to Society 5.0. This chapter attempts to identify the role of openness in promoting human-centric smart society, smart city, and smart living.

Three empirical regularities characterize markets for married workers: (1) productivity and leadership potential are predicted by intelligence; (2) assortative mating based on intelligence characterizes marriages; and (3) labor force participation declines with spouse income more rapidly for married women than for married men. Taken together these characteristics imply that labor force participation will decline for women relative to their husbands as intelligence rises. These three observations suggest a nondiscriminatory explanation for the alleged under-representation of females among corporate leaders. They imply that the women who might be predicted to win the tournament for these positions often do not enter this competition. Instead they choose employment in full time household production. Both the three regularities and the implication concerning labor force participation are empirically examined. The findings of these tests are supportive on all counts.

There are many indications that government policymakers and supporters of large-scale nuclear expansion in Poland have not seriously grappled with arguments critical of this direction of the country's power development. Instead, there is a mood of euphoric elation in these circles without even an attempt to reflect on why this kind of nuclear power is in a state of perennial crisis and lack of development prospects in Western countries.

The purpose of this chapter is to consider from an economic perspective the potential role of nuclear power in decarbonising the Polish power sector. It needs to answer two questions: why not develop large-scale nuclear power and why small modular reactors (SMRs) can be a better alternative for decarbonisation of the Polish power sector.

The primary research method used in the preparation of this chapter is a critical analysis and synthesis of the literature on the subject.

A technological revolution will offer electricity customers increasingly better alternatives. Among them there is also technology of SMRs which seems to be much less risky option in terms of its compatibility with the direction of the power sector's evolution as well as cost of sectors’ decarbonisation.

This chapter provides an overview of the current status of renewable energy projects and identifies the key success factors of well-performing public–private partnerships (PPPs). To this end, this study analyses around 1,700 renewable projects on the World Bank’s Private Participation in Renewable Energy (PPRE) database. We then follow an inductive approach for a case review and examine a 5-MW rooftop solar PPP in Gujarat, India, that had been implemented in 2012. In spite of the rapid growth of renewable PPPs, regional disparity is distinct and most PPPs have been undertaken in Latin America and the Caribbean or a few selective countries such as China or South Africa. The case study informs that the successful PPPs may be attributed to such factors as policy coordination in multi-governance systems to attract project investments, the handling of land constraints in a project planning stage, and Green Incentive given to project participants. It offers a valuable insight into the significance of well-designed PPPs for enhanced energy access in developing countries, while accelerating the global transition to renewable-based energy supply to promote sustainable development.

In this paper I draw some reflections from the experience of the Free University of Women in Milan, Italy. Through this experience it was possible to clarify some of the main issues at stake in feminist knowledge production and pedagogy such as: the relationship between women's and feminist culture, the knowledge production processes which occur among women, their epistemology, and the kind of scientific rigor of such a body of knowledge. These issues are particularly important from the perspective of teaching and transmitting feminism to a new generation of women.
